Muscle Physiology Some skeletal muscle fibers are “fast-twitch” fibers (white fibers), and others are “slow-twitch” (red) fibers. Would you expect an athlete proficient in running the 100-yard dash to have a greater proportion of red fibers or white fibers in muscles of the leg? Why? Define the following: Maximal stimulus Threshold stimulus Submaximal stimulus A skeletal muscle can be stimulated, under laboratory conditions, with a supramaximal stimulus. Is it possible for the muscle to respond with a supramaximal contraction? Explain Define a motor unit. Of what physiological advantage is a small motor unit arrangement in skeletal muscle? Explain why a latent period is observed between the application of a stimulus and contraction of the stimulated muscle. Explain, giving two causative factors, why skeletal muscle displays fatigue. Does complete or incomplete tetanus occur physiologically? Explain. Define the following: Isometric contraction Isotonic contraction Optimum length…
